linvention relates topipes' for smoking Y i v I andhasfr'eferenceparticularly to certain fitrnprov yent's'ina removablecleaning andvabsorbing fitting 'for' the smoke passage of the pipe.

Th 'objects of. ourfinvention are first to procleaning attachmentremovably carried by Eand"'pro'jecti'n'gironi fthe irnoutlfi pieceVintol the hamb'er in'the cleaning attachment in communicationwith' the'smoke passage to receive .and to retain therein, while the pipe isbeing smoked, a removable brush-like element to filter out and absorb avery substantial quantity of the nicotine and moisture passing with thesmoke from thebowl of the pipe to the mouth piece; and third to affordya mouth piece having asplit tenon to removably support the cleaningattachment.

We accomplish the objectsof our invention by means of certain structuralfeatures, one embodiment of which is described in the followingspecification, set forth in the appended claims and illustrativelyexemplified in the accompanied drawing in which:

Figure 1 is substantially longitudinal sectional view of a tobacco pipeembodying my improved cleaning attachment; Figure 2 is a substantiallytransverse sectional view of the pipe stem and cleaning attachment takenonv lines 2-2 of Figure 1;

Figure 3 is a substantially longitudinal sectional view of the cleaningattachment which is shown on a somewhat enlarged scale;

Figure 4 is aside elevational View of the cleaning attachment; and

Figure 5 is an end elevational view of the attachment.

@Referring now to the details of construction, illustrated in thedrawing, the pipe comprises a bowl Ill and shank or stem II, the latterhaving auniform bore or smoke passage I2, and being connectedto a bit ormouth piece I3 having a bore I4 forming a continuation of the passageI2. The mouth piece is removably united with the stem IIby means of aunion I5, comprising a tube provided with an annular fiange I6 at itslmid portion. The tube at its inner end I 'I is permanently mounted inthe bore I4 and one face of the flange I6 abuts the end of the stem, theother end of the tube projectingv from the mouth piece4 forms the tenonI8. The tenon I8 is cut on opposite sides and longitudinally thereof toform slits I-S.

The cleaning attachment is removably carried in the split tenon I8 andcomprises a cylindrical metal fitting provided with four longiassageofthe pipe stem; second, to pro tudinally disposed grooves 2l runningfrom' the end held in thegtenon I8 to a point just short of the oppositeend.' The grooves 2l are evenly spaced about the surface `of thefitting, and between adjacent groovesthe-material of the fitting formslongitudinal ribs 22. Each of the four ribs or radial projections 22 isstepped down slightly/ at theend of the fitting which is held by thetenon 2I8 to form a circumferential shoulder 23- 'a'gainstwhich the endof the tenon abuts when UNITED STATES PATENT OFFICE.l

The diameter of the fitting 20 isslightly less than the diameter of the smoke passage I2 in the stem IIso as to provide a loose fit between the two parts, the fitting beingactually supported in the passage by means ofthe tenon I8 which fitsverysnug in the stem.

Moisture and nicotine, which gather in they smoke passage and in thegrooves 2| when the pipe is smoked, are conveyed to the interior of thefitting 20 through the slots 2 6, and are picked up and. absorbed in the,brush portion 21 of a removable cleanery disposed within the bore ofthe fitting. The brush-like cleaner 21 is mounted upon a wire stem 28and the bristles project radially through the slots 26 and into thegrooves 2|, the stem 28 projecting outwardly through the open end of thebore and into the union I5, as illustrated in Figure 1.

In use the smoke from the bowl I0 is drawn into the smoke passage I2 inthe stern II where it contactsthe closed end of the fitting 20, entersthe orifices 24 thereof and passes along the grooves`2I between ribs 22intothe tenon I8 and then through the bore I4 of the mouth pieceI3. Thewalls of the ribs 22 cause the moisture in; the smoke to condense andcollect in the grooves. The moisture is then picked up by the brushlikecleaner which may be removed and discarded and a mouth piece removablyfitted in the stern, and a` cleaning attachment removably carried by themouth piece comprising an exteriorly grooved tubular 'fitting providedwith a closed free end having orices, each orice communicating with a,groove, and slots in the bottoms of the grooves to communicate with thebore of the tting, said slots extending between points spaced from theends o1" the grooves, and a brush-like member removably disposed in theslotted portion of the bore.
